T 0 all fwIoni t may concern.'

Be it known that I, CHEsLnY T. SMALL, a

conveyer terminates in a support 18. Journaled 1n these supports 18 is a cross shaft citizen of the United States of America, re- \l9 carrying at one end a pair of sprocket siding at the cit of St. Louis, State of M issouri, United tates of America, have 1nvented certain new and useful Conveyers, of which the following is such fa full, clear, and exact description. as will enable any one skilled in the art to which it appertains'to 'make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a conveyer and is particularly adapted for use in connection with a can filling machine such as that shown in my application No.l 184,990, filed August 8, 1917, of which the present application 1s. a division. It may, however, with or without modification, be adapted for various other purposes.

In the accompanying drawing which illus' trates one form of conveyer made in accordance with my invention, Fig. 1 is a top plan view, Fig. 2 is a side elevation, Fig. 3 is an enlarged plan vview of the outer end of the conveyer, and Fig. 4 is an enlarged section taken on the line 4-4 of Fig. 3.

5 indicates a rotary receptacle supporting table carried in frame work 6. Supported in the framework 6 is `a driving shaft 7 which may be actuated by a sprocket wheel 8, or b any other suitable gearing. Mounted on a riving shaft 7 are a pair of sprocket wheels -9 projecting upwardly through a landing plate 10. Passin around the sprocket Wheels 9 are a pair of sprocket chains 11 forming the moving part of the right hand side or division 'of the conveyer. These sprocket chains 11 are arranged in channels formed in the upper faces of T-v rails 12, projecting sli htly above the same as shown in Fig. 4 o drawings. Passing through the vertical -webs 13 of the T-rails 12 are cross bars 14. Upon each end of each of the cross bars 14 is adjustably mounted a bracket 15 secured in position by a thumb screw 16. Mounted on the brackets 15 are guide rails 17 projecting above the T-rails and adapted to hold the cans or other articles to be conveyed in proper position on the chains 11. By adjusting the brackets 15 the distance between the guidev rails 17 may be varied to accommodate cans of varying diameter. The outer end of each Side 0f the wheels 2() land 2l. One of these sprocket Wheels, preferably wheel. 20, is rigidly mounted on the shaft 19 while the other is loosely mounted thereon so as to allow the slack of the two chains 11 to be inde pendently adjusted. To accomplish this independent adjustment to the slack of the chains, I provide for each chain an arm 22 pivoted to the T-rail carrying said chain. This arm is provided at its outer end with an idler 23, bearing upon the lower part of the chain. The arm 22 is held in position by a slotted arm 25 which is connected to the said arm 22by means of a thumb nut 25.

The cross shaft 19 is provided with a gear wheel 26 meshing with a gear wheel 27 on a shaft 28 mounted in the two supports 18. This shaft 28 is provided with a pair of sprocket wheelsv 29 rigidly secured -thereto and adapted to drive the sprocket chains 11 of the left hand side or division of the conveyer. This second side or division of the conveyer is similar in .construction to the first part above described, but terminates in wheels 30, which may be sprocket wheels or pulleys, and are carried on a shaft 31 mounted in the frame 6. The wheels 30 project through a landing plate 32.

In the operation of my device the cans or other articles to be conveyed to and from the machine are to be fed to the outer end of the right hand side or division of the conveyer. The cans are evenly carried owing to the uniform movement of the two lI claim as new and desire to secure by Letters Patent of the United States is:

1. In a conveyer,the combination with a rail provided with a channel, of a sprocket chain in said channel and projecting above the same to receive an article to be conveyed, cross bars carried by said rail, and guide rails adjustably carried by said cross bars.

After being carried v 2. 1n a conveyer, the combination with a rail provided With a channel, of a sprocket chain in said channel and projecting above the same to receive an article to be conveyed, cross bars carried by said channel rail, brackets adjustahly mounted on said cross bars, and guide rails supported from said brackets above said channel rail.

3. In a conveyer, the combination with a rail provided with a channel, of a sprocket chain in said channel, cross bars passing through said rail, guide rails supported by said cross bars, and a' slack adjusting device dependingr from said channel rail.

4. n a conveyer, the combination with T-rail having' a channel in its upper face, of a sprocket chain in said channel, cross bars passing, through Vertical web of said T-rall, and guide rails adjustably supported from said cross bars.

5. in a conveying' device, the combination with a receptacle supporting table, of a Laconia driven shaft, a conveyer comprising a pair of sprocket chains driven from said shaft, a second conveyer also comprising a pair of sprocket chains, a second shaft supporting both chains of said first named conveyer but driven by one chain thereof only, and means for drivlng said second conveyer from said second shaft.

6. lin a conveyingdevice, the combination with a receptacle supporting table, of a driven shaft, a conveyer comprisinf a pair of sprocket chains driven from sai shaft, a second conveyer, a second shaft supporting both chains of said rst named conveyer but driven by one chain thereof only, and means for drivlng said second conveyer from said second shaft, said means including reversing gearing.

In testimony whereof, I have hereunto set my hand and aflixed my seal.
